Last Monday evening, we staged www.beta.facebook.com with the code we planned on pushing to the full web tier the following day. We did so with the intent of giving developers a full 24 hours to confirm that their applications were still fully operational and that the features, updates, and bug fixes checked in over the course of the preceding week weren't causing applications to break in ways that seriously impacted users.

From now on, we plan on updating www.beta.facebook.comevery Monday evening so our developers have ample opportunity to make sure their applications are still working as expected. The beta site is accessible to any user with the developer app installed. If everything checks out, then you know your applications will work beautifully once all the changes go live. If you find a problem, you can file a bug report and we'll work to fix the bug as soon as we hear of it. We're hoping the new beta site will be an effective way to catch problems that might otherwise get pushed out in front of users.

If you find a bug, then you can file a bug report at bugs.developers.facebook.com. Very soon, we'll set up a special section dedicated to pre-release bugs, but for the time being, just mention that the problem exists on the beta site so we know where to look for it.
